Specification of Letters Patent.

Patented Dec. 30, 1919..

Application filed September 6, 1919. Serial No. 322,111.

To all whom it may concern:

Be it known that I, RUPERT N. OYSLER, a citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented certain new and useful Improvements in Wrenches, of which thefollowing is a specification, reference being had tothe accompanyingdrawings.

This invention relates to wrenches, and has for its object to provide adevice of this character, the handle of which revolves and includes atits ends a plurality of nut engaging sockets of various sizes which maybe instantly adjusted.

Another object of this invention is to provide a novel mechanism. forlocking the sockets firmly in position when in use.

A still further object of the invention is to provide a wrench of thischaracter having pivoted to its end a terret including a plurality ofsockets which may be instantly rotated to bring the desired socket intoposition and then firmly lock it to the rotating handle.

These objects are attained by the mechanism illustrated in theaccompanying drawno in which:

T igure 1 is a perspective view of the complete wrench.

Fig. 2 is an end View of the terret.

Fi 3 is a detail view of the sprin and key or securing the terret to thehan e.

Referring to the drawings, 5 indicates the shank of a handle, having itsend portion 6 bent outwardly and upwardly and provided at its end with aknob 7 which is pivoted thereto. A hand grip 8 iscarried by the shank 5of the handle. The remaining end 9 of the handle is bent at right anglesto the shank 5 and is provided with a groove or he way 10. A terret l].is provided and includes a plurality of radiating nut engaging sockets12. These sockets are of various sizes. The central portionot the terret11 has a central bore 13, through which the end 9 or the handle extends.It washer id is disposed on the end of the handle, and retained by meansof a screw to prevent disengagement of the terret from the handle.Communicating with the bore 13 IS a plurality of keyways 15. Slidablymounted in the keyway 10 is a key 16 provided with an operating fingerpiece 17 adapted to withdraw the key 16 from the keyways 1n the terret'11 when it is desired to adjust the terret.

Encircling the key way and end 9 of the handle 1s an expansion spring 18secured at .one end to the handle and at its other end to the key 16with the finger piece 17 and is intended to urge the key outwardly fromthe end of the handle into the registering keyways l5 oithe'terret andto prevent disengagement of the'key 16 from the keyway 10. i

In operation, to bring the desired wrench engaging socket into osition,the finger piece 17 is grasped by e operator so as to withdraw the key16 from the keyway of the terret. The terret is then rotated to bringthe desired socket in position, whereupon the finger piece is releasedand the key, throu h the action of the spring, is forced into t eregistering keywav in the terret. Dur' the operation oithe wrench, theknob 'l is held stationary while the handle 8 is grasped to revolve thehandle and terret.

From the foregoing description, it will readily be seen that this wrenchcan be instantly adjusted to accommodate various sizes of nuts, and inview of its novel form,

of handle permits greater force to be applied to the nut in thetightenin or loosening operation. It is particular y ada ted for use ondemountable automobile w eel rims, and will also be found especiallyuseful for the various parts of the engine. The various sizes ofsockets, however, permit its unlimited utility wherever a wrench isdesired.

at is claimed is 1. In a wrench, a rotatable handle havin a grooveextending through one end thereo a nut engaging member having a centralbore, and a plurality of recesses communicating with the bore, saidmember being rotatable on the handle over a. portion of the groove, anda key slidabie in the groove and projecting above the surface of the handle, one end of the projecting portion engaging a registering recess 0the bore to key said member to the handle.

2. In a wrench, a rotatable handle havin a groove extending through oneend thereo a nut engaging member having a central bore, and a pluralityof recesses communicating with the bore, said member bein ro tata'ble onthe handle over a portion 0? the groove, and a key slidable in thegroove and projecting above the surface of the handle, one end of theprojecting portion engaging a registering recess of the here to key saidneeeeee member at its pivotai connection to the registering recess ofthe bore, the opposite handle. surface of the end portion engaging the3. In a Wrench a rotatable handle homing groove within the bore and aspring secured a groove extending through one end thereof, at one end tothe handle and surrounding a nut engaging member having a central thegrooved portion thereof and the key for I bore and a plurality ofrecesses eonnnunicetoperating and preventing disengaging of the ing withthe bore, said member being" roket from the handle.
